KNOTTlNG MECHANISM FOR GRAIN-BINDERS.

ECIFICATION forming part of Letters Patent No. 319,167, dated June 2, 1885.

Application filed July 3, 1884. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN F. APPLEBY, of Minneapolis, Minnesota, have invented a certain Improvement in Knotting Mechanisms for Grain-Binders, of which the following is a specification.

My improvement relates to knotting mechanism of the type in which a single cam serves to operate the cord-gripping device, to impart 1c the lateral movement to the knotter after the knot is partially formed,'and to give motion to the swaying knife which severs the bindingcord between the knotter and the grippingdisk. In my present invention the same earn 1 5 performs the additional function of giving the necessary rocking motion to the tucker,which at the proper time tucks the binding-cord under the knotting-bill. Other features of my present improvement are, first, that the seg- 2o mental gear upon the face of the knotter-opcrating wheel at the proper time engages directly with and rotates a bevel-pinion affixed to the knottershaft; and, secondly, that a stationary guiding-hook between the knotter and 2 5 the grippingdisk catches and holds the hinding-cord up, and thus maintains it in a position in which it intersects the path of the movable knife which severs it.

The accompanying drawings of knotting o mechanism embodying my invention are as follows:

Figure 1 is an elevation, partly in section, of the side toward the grain-platform,showing the swinging frame in which the knottershaft is carried in the vertical position which it occupies while the knotter-shaft is being r0- tated. Fig. 2 is a face view of the knotteroperating wheel in the position in which it is represented in Fig. 1. Fig. 3 is a similar ele- 1o vation with some of the parts broken out, showing the frame in which the knotter-shaftis journaled swung outward from its vertical position by the operation of the lcnotter-opcrating wheel. Fig. 4 is a face view of the k uotter-opcrating wheel in the position in which it is represented as occupying in Fig. 3. Fig. 5 is an elevation of the drive-wheel side of the knotting mechanism. Fig. 6 is a vertical section taken through the line a: a: on

Fig. 5. Fig. '7 is a horizontal section taken through the line y g on Fig. 8, which is a vertical section taken through the line 2 2 on Fig. 7.

In its general appearance the knotting mechanism shown in the drawings somewhat resembles that shown in my pending application, serially numbered 115,961, filed December 29, 1883. .The knotter-operating wheel A is affixed to the horizontal shaft A, having a bearing in the upper part of the frame B. The knotter-operating wheel is of the usual cupped shape, and has upon one edge the projecting flange a, on the face of which is formed the slightly-beveled rack a. The inner side face, 0, of the knotter-operating wheel is pro vided with the cam-groove C. At the proper time during the rotation of the knotter-operating wheel, the rack a engages and turns the bevel-pinion D, which is aflixed to the knottershaft D. The knotter-shaft is journaled in the swinging frame E, hung upon the pivot E, having a horizontal bearing in the frame B. An

arm, 6, affixed to and projecting laterally from I the swinging frame E, is provided at its end with the anti-friction roller 6', which is engaged by the cam-groove O, by the operation of which the necessary swinging motion is given to the frame E and to the kuotter-shaft D. The knife F, for severing the binding-cord, swings on the pivot f, inserted in the frame 13. The swinging of the knife F is effected by the pin f, projecting laterally from the swinging frame E and engaging a slot,f' in the upper part of the knife-arm. The organization in respect to the manner of transmitting motion to the movable knife is similar to that described in my pending application, serially numbered 115,961; but in the present case I employ the stationary guide G, which is inserted in the frame B, for the purpose of holding up the binding-cord between the knotting-bill and the gripping device and insuring that the cord shall intersect the path of the movable knife, and be severed when the swinging frame E is swung outward and the knife swung in the opposite direction.

The gripping mechanism consists of the usual notched wheel, H, and grooved arm H. The shaft of the disk H is provided with the usual ratchet-wheel, h. The intermittent rotation of the gripping-disk is effected by the usual reciprocating pawl, I, pivoted in the arm j, projecting laterally from the rock-shaft J, which is also provided with the arm J, having at its end the anti-friction roller J which engages the cam-groove G.

In the respects so far described the organization of the mechanism for operating the gripping-disk and imparting the desired motions to the swinging frame and to the movable knife is similar to that shown and described in my pending application, serially numbered 115,961. In the present case the k notter-operati ng wheel is made to perform the additional function of operating the tucker K. This is effected by means of the arm J projecting downwardly from the rock-shaft J, and linked at its lower end by means of the pitman k to the crank K,

affixed to the upper end of the vertical shalt 7a", to the lower end of which the tucker K is affixed. The tucker-shaft k is provided with vertical half-bearings in the cars B 15, cast on the frame 13, in which bearings it is held by the caps 13 B", east in one piece with the plate B which is fastened in position by the screwbolt 13'. It will be seen that when the rockshaft Jis rocked in such a direction as to cause the impelling-pawl I to turn the gripping-disk the arm J swings away from the bearing of the tucker-shaft, and by turning that shaft swings the tucker K under the knotting-billd. The bindingcord, extending from the knotting-bill to the gripping-disk, is caught in the bight of the guide G, and therefore, notwithstanding the carrying downward of the ends of the binding-cord caught in the grippi rig-disk, that portion of the bindingcord extending from the knottingbill to the guide is tated by the rack upon the knotter-operating wheel.

2. In combination with a knotting-bill, a movable knife, and a rotating gripping-disk,

substantially such as described, a guide, G,

for preventing the binding cord from being swayed downward by the movement of the gripping-disk, and thereby holding the hind ing-cord extending from the gripping-disk to the knotting-bill in a position in which it intersects the path of movement of the movable knife.

3. In knotting mechanism, the combination of a knotterjournaled in a swinging frame, a gripping disk operated by a reciprocating pawl,mechan1sm for severing the bllldlllg-COId and disengaging the knotter from the loop,and a tucker for tucking the bindingcord under the knottingbill, in combination with a single knotter-operating wheel.
